What was the expected behaviour?

No crashes

Was it tested on latest react-native-navigation?

• I have tested this issue on the latest react-native-navigation release and it still reproduces.

Help us reproduce this issue!

No response

In what environment did this happen?

React Native Navigation version: 8.8.1/8.8.3
React Native version: 0.81.6
Has Fabric (React Native's new rendering system) enabled: yes
Node version: 24
Device model: Any
Android version: Any

Start at the NavigationTurboModule.setRoot call shown in the stack trace and trace the path to the constructor that receives a null context. Reproduce the intermittent Android crash around setRoot, identify its triggering conditions, and verify that the same path no longer raises this NullPointerException.
